McShay ranks Pac-12 by 'tiers'

ESPN NFL draft guru Todd McShay has broken down his list of top-100 draft prospects by seven tiers in order of draft gradeInsider.

He writes: "The tiers show which portions of the class are deep and which are lean. There are some lean tiers near the top of the board, but the class is solid in Tiers 3 and 4."

His list includes 15 Pac-12 players. Here's how things stack up as well as his explanation for each tier.

Tier 1: These are the elite prospects, those who have the potential to come off the board in the top five overall picks.

1. Andrew Luck, QB, Stanford (Luck's 99 grade is the best in the draft, two points higher than Baylor QB Robert Griffin III)

3. Matt Kalil, OT, USC

Tier 2: This tier is composed of players who are a notch below elite but are still top-10 quality.


Tier 3: The prospects will offer good value between picks 10 and 20.

14. David DeCastro, OG, Stanford

Tier 4: These prospects have the tools to be good value picks in the late-first round.

26. Jonathan Martin, OT, Stanford

30. Nick Perry, DE, USC

Tier 5: These are the players teams will begin targeting as value picks early in Round 2 should they fall out of Round 1.

34. Coby Fleener, TE, Stanford

39. Nick Foles, QB, Arizona

50. Brock Osweiler, QB, Arizona State

52. Mychal Kendricks, LB, California

Tier 6: This tier contains prospects who are worthy of mid-to-late-second-round consideration.

62. Mitchell Schwartz, OT, California

63. Alameda Ta'amu, DT, Washington

67. LaMichael James, RB, Oregon

Tier 7: These players rank as solid third-round prospects.

87. Tony Bergstrom, OT, Utah

96. Chris Polk, RB, Washington

100. Trevor Guyton, DE, California
